摘要 |
An optical device for processing radiation that includes a beam splitter and a plurality of radiation processing parts arranged to process the characteristics of different radiation components separately, The polarizing beam splitter includes a wire grid polarizer, a first transparent plate arranged adjacent one side of the polarizer and a second transparent plate arranged adjacent the other side. Each of the first and second plates have substantially equal optical thickness profile.
